So I have managed to fuck up a rather simple situation. Girl A is a girl who is sleeping with me in a friends with benefits situation except we are also best best friends. I hae been doing this for a month. Girl B is part of the same friend group as Girl A and me and we are rather good friends, but not as good as me and Girl A. After an argument that Girl A and I had, I made a move and slept with Girl B. Girl A and I are now in the process of recovering from the argument which now that I think about it wasn't that bad. I am a college freshman, if that can help your responses. What should I do?

From what I think I have three scenarios, The opportunistic scenario, the walk away scenario, and the honest scenrio

opportunistic- i continue sleeping with both girls walk away- I know Girl B wont tell Girl A about the hookup, so I'll just continue with Girl A and ends things with Girl B honest- tell Girl A everything and most likely ask for forgiveness, probably the most BP scenario
